BACKGROUND Technical Field

The present invention relates to an optical image capturing lenses. Moreparticularly, the present invention relates to a compact optical imagecapturing lenses applicable to electronic products.

Description of Related Art

In recent years, with the popularity of mobile products with camerafunctionalities, the demand for miniaturizing an optical image capturinglenses is increasing. The sensor of a conventional photographing camerais typically a CCD (Charge Coupled Device) or a CMOS (ComplementaryMetal-Oxide Semiconductor Sensor). As advanced semiconductormanufacturing technologies have allowed the pixel size of sensors to bereduced and compact optical image capturing lenses have graduallyevolved toward the fields of higher megapixels, there is an increasingdemand for optical image capturing lenses featuring better imagequality.

A conventional optical image capturing lenses in a portable electronicproduct typically utilizes a three-element lens structure. Such aconventional optical image capturing lenses has a first lens elementwith positive refractive power, a second lens element with negativerefractive power and a third lens element with positive refractivepower. The first, second and third lens elements are arranged in thisorder from an object-side to an image-side. Although the three-elementlens structure is compact, it is not able to produce high qualityimages.

Further, another conventional compact optical image capturing lensesprovides a four-element lens structure. The first lens element and thesecond lens element of the four-element lens structure are two glassspherical lens elements which are attached to each other to form adoublet lens for eliminating chromatic aberration. However, this lensstructure requires a longer total optical track length caused byinsufficient degrees of freedom in setting system parameters due to toomany spherical lenses allocated. Moreover, it is not easy to attach theglass lenses, and thus the manufacturing process for forming the glassdoublet lenses is difficult. Therefore, a need exists in the art forproviding an optical image capturing lenses for use in a mobileelectronic product that has excellent imaging quality without too longtotal track length.

Moreover, the problem of the foregoing optical image capturing lenses isthat both of the image quality and the production cost can not bemaintained. In detail, two different lenses assemblies should be usedwhen photographing a near object and a far object. However, thedifficulty or the cost of the production would be increased by preparingtwo lenses assemblies or one lenses assembly which can be adjusted.
